```
public SimpleInstruction(byte opcode,
                         int constant)
```
    Creates a new SimpleInstruction with the given opcode and constant. Automatically adapts the opcode if it has an embedded constant and the constant lies within the supported range. If the constant doesn't lie within the supported range, it must be adapted before the instruction can be written out.
